a reproducer application
If an application is compiled with Intel compiler, line numbers are displayed
incorrectly if the line contains line break.
A reproducer application (line_numbers.c) is attached.
Steps to build and run the test:
icc -O0 -g line_numbers.c -o line_numbers_icc
valgrind -q ./line_numbers_icc
Expected result (reported for gcc-compiled application):
==xxxx== Invalid write of size 4
==xxxx== at 0xxxxxxx: main (line_numbers.c:8)
==xxxx== Address 0xxxxxxxx is 4 bytes inside a block of size 40 free'd
==xxxx== at 0xxxxxxxx: free (vg_replace_malloc.c:530)
==xxxx== by 0xxxxxxx: main (line_numbers.c:7)
==xxxx== Block was alloc'd at
==xxxx== at 0xxxxxxxx: malloc (vg_replace_malloc.c:299)
==xxxx== by 0xxxxxxx: main (line_numbers.c:5)
==xxxx==
Actual result:
==xxxx== Invalid write of size 4
==xxxx== at 0xxxxxxx: main (line_numbers.c:8)
==xxxx== Address 0xxxxxxxx is 4 bytes inside a block of size 40 free'd
==xxxx== at 0xxxxxxxx: free (vg_replace_malloc.c:530)
==xxxx== by 0xxxxxxx: main (line_numbers.c:7)
==xxxx== Block was alloc'd at
==xxxx== at 0xxxxxxxx: malloc (vg_replace_malloc.c:299)
==xxxx== by 0xxxxxxx: main (line_numbers.c:7)
==xxxx==
